Specification of Letters Patent.

Application led .Tune 8, 1916. Serial No. 102,571.

To all '1r/Loin it may Concern:

Be it known that I. Josemi A. LESPER- .mera a subject of the King of Great Britain. residing at Number 300 Champlain street. Montreal. Province of Quebec, Canada. have invented certain new and useful Improvements in Heaters; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to improvementsI in heaters and` more particularly to a heater adapted to be inserted into a bod)1 of water for raising the temperature of the water. and an object of the present invention is to provide a compact transportable heater of this character which will be siniple, strong. durable. and el'licient when in use and one which will be comparativel)v inexpensive in the cost of manufacture thereby rendering the same commercially desirable.

'ith the above and other objects in view which will hereinafter appearfas the description continues, the invention consists of the novel features of construction and the formation of parts as will be hercin` after more fully described and particularly pointed out. in the appended claim.

In the accompanying drawings is shown the simple and preferred form of the invention2 it being, however. uudertood that no limitation is necessarily made to the precise structural details herein exhibited but the right is hereby reserved to any changes or alterations that may be had and come within the scope of the invention without departing from the spirit thereof or sacrificing the etiieiency of the same.

1n the accompanying drawings;

Figure 1 is a vertical section through a rcontainer having the heater arranged therein and the latter being shown in side elevation;

llig. 2 is a similar section showing the heater in sectional View;

Fig. 3 is a horizontal section taken on the, Aline 3 3 of Fig. 1; and,

Fig. 4 is a horizontal section taken on the line 4-4 of Fig. 1.

On reference being had to the accompanying drawings wherein like and corresponding parts are designated by similar l both when it is desired.

reference characters through the several views.

The numeral l indicates a container in which the heater is to be arranged and this container may be placed Within a body of water or like fluid which is to be heated and the lower end of the container l is provided with a weighted bottom preferably made of lead so that the container Will sink withiny the fluid in which it is inserted and be retained in an upright position.

In the accompanying drawings the heater is shown comprisingr a gas heating section and an electric heated section combined in one unit` but of course it is to be understood that either heating section may be used o1' Suspended Wit-hin the upper end of the container 1 is a support 3 having a flange t adapted to project over the upper end of the container 1 for supporting the heaters within the container. l `ormed with the lower edge of the -support l are a pair of diagonally extending bars` and supported b v these bars is a hollow' standard (i. Secured to the lower end of the standard are the two right angular bars i' and supported upon the bars 7 is afplate S. Secured to the plate 8 by means lof the bolts 9 is a hollow cylindrical casting 10 and arranged within the outer wall of thisI castine a plurality of perforations 1l. (lonimunit-ating with the interior of this casting l() is an inlet pipe l2 and slidably connected with the upper end of this inlet pipe 12 is a supply pipe 13 which has arranged therein the air controlling valvc 14 and the gas 4cock 15. This pipe 13 may be connected to a suitable gas supply in any preferred or well known man-- ner or b v connecting flexible. hose to the end 1G of the supply pipe. A tube 17 is also secured within the support 3 having its lower end terminating upon the outer periphery of the casting 10 and its upper end extending beyond the container; The, casting l0 provides a gas burner for the heater when gas is supplied thereto through the pipe 1Q and by applying a lighted match or other llame to the upper end of the tube 17 the same. will be drawn down through the tube where the Haine will ignite the escaping gaspassing through the perforations 11.

Also secured to the bar 7 is a ring of insulating material 18 and spaced from this ring 18 is an insulating disk 19 the lattei` of which is adapted to rest upon the bottom of the container and is secured to the ring` i8 by means of the supports 20. The outer peripheries of the ring 18 and the disk 19 notched as at 2l. as better shown in lfigs. 3 and 4: and secured to the lug projections .formed bv making these notches are a php rality of electrically connected 'resistant Coils 2%. rliese coils ere connected in series with the lead wir-es 23 which extend upwardly through the standard G and are connected with the terminals 24.

Frein the foregoing it is obvious 'that when current is supplied to the terminals 24 and directed to the coils heat will be throvs'nol thereby providing an electric heater for the device whiehniay also be used in connection with the gas burner for providing; additional heating means. llt is apparent that 'the container l may be inserted into the body of water which is to be heated and that the electric heater or the heater may either be brought into use for raising the temperature of the water or both of the heaters may be jointly used thereby furnishingr more heat units to the moroso container. llt is also to be understood that the device may be used for heat-.ing objects other than bodies of water and that the respective heaters may beused severally or jointly.

Having thus fully described my invention, what l claim as new and desire to secure by Letters Patent is:

In a heater o. the character described comprising a container having a Weighted bottom and its upper end open7 a support suspended within said container, a standard carried by said support, a pair of cross bars secured to the lower end l said Standard, an insulating; ring carried by said cross bars, an insulating disk suspended from said ring,

the outer periphery of said ring and said disk being notched, a plurality of coils connecting said notched peripheries of said disk and said ring, and lead Wires connected to said coils and extending upwardly through said standard for the purpose set forth.

In witness whereof l have hereunto set my hand. l

JOSEPH A. LlflSlERANCE.
